Title: Arrangement for simultaneous and direct comparison of the measurement accuracy of two different laser interferometers
Inventor: SCHUESSLER HANS-H DIPL-ING DR
IPC: G01B9/02
Filed: 1983-10-27
Granted: 1985-02-28
Abstract: The invention relates to an arrangement for simultaneous and direct comparison of the measurement accuracy of two different laser interferometers. In order to obtain as low as possible a comparison uncertainty for the arrangement, and to ensure that unavoidable fluctuations inside the propagation medium of the measurement beam have an identical effect for all laser interferometers used in comparison, it is provided that the two interferometers irradiate a common interferometer divider from which the two measurement beams extend in the same position in one and the same measurement section to a common measuring reflector. Temperature-induced displacements of the components involved likewise have an identical effect for both measurement beams and do not influence the result of the comparison. In order to be able to distinguish the measurement beams, which extend in the common radiation corridor, from one another, they must either extend in a laterally offset fashion or must have a different state of polarisation, or run in opposite directions inside the radiation corridor. The outlined comparison arrangement also permits comparisons of accuracy between laser interferometers of different systems and different colours.
Patent DE-3405869-C1 (DE)
Title: Lagging unit for mine support and method of manufacturing it
IPC: E21D11/15
Filed: 1984-02-18
Granted: 1993-01-28
Abstract: Lagging unit for mine support, with longitudinal bars, cross bars, suspension hooks bent at one end of the unit from the longitudinal bars and having a free suspension-hook leg, and coupling elements arranged at the other end of the unit. The longitudinal bars and the cross bars are welded to one another at their intersections to form a steel-bar mat. In the combination with another unit end of an adjacent unit of identical design, the suspension hooks can reach behind a steel bar, while the allocated coupling element can be brought into engagement with the free suspension-hook leg. The coupling elements are integrally formed on a continuous transverse coupling bar, specifically in the grid dimension of the longitudinal bars, and the transverse coupling bar is welded with the coupling elements in the area of the longitudinal bars onto the steel-bar mat. The method of manufacture starts from a straight steel bar which is first provided with the coupling elements and is then welded onto the steel-bar mat. <IMAGE>
Patent DE-3424167-C1 (DE)
Title: Envelope which can be filled automatically
Inventor: WEGENER GUENTER
IPC: B65D27/14
Filed: 1984-06-30
Granted: 1985-09-26
Abstract: On an envelope which can be filled automatically and whose side flaps are connected to the bottom flap in each case via a layer of adhesive along the side flaps, said layer of adhesive is made of an adhesive which is coloured and/or made fluorescent so that the adhesive is visible, or can be made visible by illumination, if it has also been applied outside the areas provided for gluing due to faults or inaccuracies. Faulty envelopes can thus easily be recognised already during manufacture and separated so that interferences during further processing, in particular during automatic filling, as a result of faulty application of adhesive are ruled out.

Title: Electrical heating body for heating gaseous media, and a method for its production
Inventor: HILLINGER ERICH
IPC: H05B3/32
Filed: 1985-02-15
Granted: 1986-07-10
Abstract: In the case of electrical heating inserts, in the case of which the heating coil is arranged in an exposed manner, by means of a plurality of insulating connecting elements or supporting elements, on a carrier part of the insert, a considerable amount of manual work is required in order to install the heating inserts. This is because the connecting elements or supporting elements (which generally consist of ceramic) are highly susceptible to fracture and to a large extent also have relatively large dimensional tolerances, that is to say have properties which would make mechanical installation very difficult. Furthermore, it must be taken into account that the heating coil itself is very unstable. In order to solve these problems and to enable mechanical and hence cost-effective manufacture of such heating inserts, the invention proposes that the insulating supports which carry the heating coil be integrally formed in one pressing process directly on the carrier part of the heating insert, from a curable ceramic mixture. <IMAGE>

The pressurized container has an air-extraction connection. The intake end of the preliminary air heater communicates with the air-extraction connection. Its outlet end communicates with the air box in the combustion chamber through an air line that extends through the pressurized container.

Title: Arrangement for recovering heat in heating boilers
Inventor: SKOBERNE WILLI
IPC: F24D12/02
Filed: 1987-10-08
Granted: 1988-12-01
Abstract: An arrangement for recovering heat in a heating boiler (1) comprises, in the flue-gas duct (3), a heat exchanger (8) which is connected between a heating flow pipe (14) and a heating return pipe (21). By means of a three-way valve (17), the heat exchanger (8) can be bypassed via a bypass pipe (22) when the temperature in the flue-gas duct (3) is so low that the heat exchanger (8) would not absorb any heat. A second heat exchanger (9) is arranged downstream in the flue-gas duct (3) and is connected to the heating return pipe (21). By recovering heat from the flue-gas duct (3), on the one hand the efficiency of the heating installation is considerably increased and on the other hand the flue-gas temperature is reduced to such a degree that a plastic tube (5) is sufficient for carrying away the flue gases. <IMAGE>

Title: Control method for reducing the power loss of the main thyristor of a D.C. chopper converter during the braking mode of a vehicle motor
IPC: B60L7/22
Filed: 1988-09-28
Granted: 1989-11-23
Abstract: The intention is to disclose a control method for reducing the power loss of the main thyristor of the D.C. chopper converter, which thyristor is constructed as a turn-off thyristor, during the hazard braking mode of a vehicle motor when the D.C. chopper converter circuit is operating with disconnected brake rheostatic controller and a contact line network is disconnected, during hazard braking mode, from the mains capacitor which is connected upstream of the D.C. chopper converter. The control method is characterised in that the drive level of the brake thyristor is adjusted by means of a control variable (wU) for the voltage (UC) at the mains capacitor, which voltage (UC) is predetermined in terms of its characteristic curve as a function of the rpm (n) of the vehicle motor. Furthermore, the frequency of the ignition signals (ZHT and ZBT) is predetermined in terms of the characteristic curve for the main thyristor of the D.C. chopper converter and for the brake thyristor as a function of the rpm (n) of the vehicle motor. <IMAGE>

Title: Carrier projectile for sub-munition
Inventor: SCHLEICHER ULRICH DR
IPC: F42B12/62
Filed: 1990-01-23
Granted: 1998-05-14
Abstract: The projectile has a braking parachute and holding devices between the projectile casing and a base having an expandable pressure accumulator. The pressure accumulator is located between the projectile base and a hollow base covering the braking parachute. The projectile base on expansion of the pressure accumulator draws out the braking parachute via a line. The pressure accumulator is a pressure bag (13), which is connected via a check valve (16) to an opening (15) of the projectile base (3). On firing, the drive charge gases arising fill the pressure bag (13) through the opening (15). The opening is so formed that the internal pressure of the pressure bag remains less than the pressure of the drive charge gases in the weapon barrel. The opening is closed by a burst membrane (117), which breaks on firing.
